Plugs from France plug directly into wall sockets in South Korea, and mains voltage is compatible (230V vs 220V). Still verify that your high-power appliances support 220V. Electrical frequency also differs (50Hz vs 60Hz). Modern digital chargers are dual-frequency (50/60Hz), but analog motor-driven clocks or clippers may run slightly faster or slower.

South Korea uses Type C, F. Look for 3-pin adapters if your appliance uses a grounded plug.
